中文摘要:
      以地处宁夏吴忠市利通区的国家农业科技园区种植业核心区为例,介绍基于3S技术的大比例尺土壤养分图制图过程,主要包括基于DGPS定位的网格取样法土壤样品采集、基于土壤养分系统研究法(ASI)的样品分析、基于Quickbird遥感影像和ArcGis9平台的研究区边界和非耕地区域数字化、土壤养分数据库的建立及其与样点属性数据库的链接、基于Kriging方法的空间插值和土壤养分图绘制等过程。这一制图方法具有简捷、高效、准确、清晰等特点,可以更好地反映土壤养分的空间分布特征,为精准施肥服务。
英文摘要:
      Taking Wuzhong State Agro-Hi-Tech Demonstration Zone as an example, this paper explained the large\|scale soil nutrients mapping based on Quickbird image, Arcgis 9 desktop and DGPS, as well as necessary field and lab works.The approach followed DGPS-based field 100 m grid soil sampling, ASI soil testing, Quickbird\|based field surveying for farmland and settlement boundary, and soil nutrients database, spatial interpolation and soil mapping.This 3S-based soil nutrients mapping approach, integrated into ArcGis geodatabase framework, was efficient and accurate.It facilitated greatly single and comprehensive nutrient assessment and fertilization recommendation.
